'I was this morning called by a trifling circumstance to notice the peculiar motions of camphor on water: I should not have mentioned the simple circumstance but that I thought the effect was owing to electricity, and I supposed that if you were acquainted with the phenomenon, you would notice it. I conceive, too, that a science may be illustrated by those minute actions and effects, almost as much as by more evident and obvious phenomena. Facts are plentiful enough, but we know not how to class them; many are overlooked because they seem uninteresting: but remember that what led Newton to pursue and discover the law of gravity, and ultimately the laws by which worlds revolve, was—the fall of an apple.
